Pixel Art Details

So ... I was thinking a lot about who to choose. It was hard, cuz I have a lot of options (Johnny Cash, Jack White, Frank Sinatra, Bob Dylan, Jimi Hendrix). I stopped on Bob Dylan (made a very quick sketch and then I decided that it's ok).

Soooo ... That was a nice experience c:
Thanks to Discord guys for the help
